Go has two general purpose generic data structures built into the language: slices and maps. Slices and maps can hold values of any data type, with static type checking for values stored and retrieved. The values are stored as themselves, not as interface types. That is, when I have a[]...
Unbuffered channels combine communication—the exchange of a value—with synchronization—guaranteeing that two calculations (goroutines) are in a known state. There are lots of nice idioms using channels. Here's one to get us started. In the previous section we launched a sort in the back...
The easy way to create a slice and initialize with a value is as shown below. Instead of declaring a slice variable first, and then initializing the values separately, you can combine them together. os := []string{"Linux", "Mac", "Windows"} fibonacci := []int{1, 1, 2, 3, 5, ...
-buildmode=shared Combine all the listed non-main packages into a single shared library that will be used when building with the -linkshared option. Packages named main are ignored. -buildmode=exe Build the listed main packages and everything they import into executables. Packages not named ...
The function takes two arguments: the iterator and the function that defines how to combine the iterator elements. Here's an example: func sum(x, y int) int { return x + y } func main() { numbers := iterium.New(1, 2, 3, 4, 5) filter := iterium.Accumulate(numbers, sum) ...
in C, it's perfectly OK to return the address of a local variable; the storage associated with the variable survives after the function returns. In fact, taking the address of a composite literal allocates a fresh instance each time it is evaluated, so we can combine these last two lines...
Methods can be implemented for any type; structures represent data while interfaces represent abstraction; and so on. Orthogonality makes it easier to understand what happens when things combine.当然一旦设计正交,需要的概念也变得很少。 speed of compilation ...
